VarietiesĬitrus belong to the family Rutaceae, which includes the genera of true citrus fruit, i.e. Patios and small courtyards are suitable for tub trees such as Meyer lemons, cumquats and calamondins. If trees are planted in tubs, they will need to be in the sun for at least part of the day to maintain healthy growth. Avoid positions that are low and frost-prone, or exposed to strong winds, particularly sea winds. Maximum sunlight is desirable for fruit growth, setting and maturity. They will not tolerate very acidic or alkaline conditions, preferring a soil pH between 6–7. Where to establishĬitrus trees grow best in deep (50 cm), well-drained, sandy loam soils. Rough lemon is a frost-sensitive rootstock and sweet orange moderately susceptible, while citrange is cold-hardy and Poncirus trifoliata very cold-hardy. cold hardy: Seville, mandarin and Meyer lemon.moderately susceptible: grapefruit, pummelo and sweet oranges.These usually grow continuously and are susceptible to injury even by very light frosts. very sensitive: citron, lime and lemon.
This often influences where certain varieties or types can be grown successfully, as regular frost damage must be avoided. The cold-hardiness of fruiting citrus types varies significantly.
Provided adequate irrigation is available, trees can tolerate hot conditions, although exposed fruits can be sunburnt. However, they will generally not grow on the tablelands, where severe frosts can damage the trees and fruit. Location ClimateĬitrus are considered subtropical but will grow in most areas of New South Wales, from the coast to the western inland and as far south as the Murray Valley. Home-grown fresh citrus fruits are nutritious to eat or to juice for healthy and refreshing drinks. Apart from the convenience of having fresh fruit readily available, citrus trees make their own contribution to the home garden with their shiny green foliage, pleasant-smelling blossom and attractive fruit colour.
